Despite advances in the scientific methodology of witness testimony research, no sound measure currently exists to evaluate perceptions of testimony skills. Drawing on self-efficacy and witness preparation research, the present study describes development of the Observed Witness Efficacy Scale (OWES). Factor analyses of a mock jury sample yielded a two-factor structure (Poise and Communication Style) consistent with previous research on witness self-ratings of testimony delivery skills. OWES subscales showed differential patterns of association with witness credibility, witness believability, agreement with the witness, and verdict decision. Juror gender moderated the impact of Communication Style, but not Poise, on belief of and agreement with the witness. Results are discussed with attention to application of the OWES to witness research and preparation training.

Prison rape is a pervasive and serious problem affecting many male inmates in U.S. prisons. This paper reviews the literature on prison rape prevalence, victimization risk factors, and the psychological and non-psychological sequelae of prison rape. We address several areas of inquiry needed to guide research and facilitate solutions to the problem of prison rape, especially given the context and intent of the Prison Rape Elimination Act (PREA) passed in 2003 by the U.S. Congress. Mental health correlates remain to be studied; for example, the complex post-rape symptoms of prison rape survivors do not appear to be captured by current diagnostic nomenclature. To date, psychology has been largely silent on the issue of prison rape but may have much to offer in terms of describing and treating the psychological impact of victimization, documenting the personal and situational risk and protective factors associated with prison rape, and in designing programs and policy to reduce prison rape.
